This is the playset that enables children to design and build a custom racetrack and a car to drive it. Using the included swivel-tipped hex screwdriver, a child assembles a 3"-long car from 11 metal and plastic pieces including hoods, fenders, and tires, that can also be interchanged with supplemental cars (sold separately below). The course is assembled using 20 foam interlocking pieces including 12 curved sections for building hairpin turns, four "Y"-shaped sections that create forks for alternative routes, and four straightaways for high-speed finishes. Also includes driving obstacles such as racing cones, barriers, and tire stacks. Ages 6 and up.
